Abstract
Tracking the inheritance patterns of proteins (TrIPP) is a live-cell imaging technique used for tracking maternal protein segregation patterns between mother and daughter cells during asymmetric divisions of budding yeast. We use the photo-convertible fluorescent protein Dendra2 fused to a protein of interest (POI). Irreversible conversion from green to red fluorescence allows for parallel monitoring of old and new proteins for several generations. Single-cell quantitative image analysis of time-lapse microscopy gives synthesis and decay rates, as well as segregation patterns of the POI.
For complete details on the use and execution of this protocol, please refer to Auboiron et al. (2021).
